What happened?

Simply drag the earth, zoom in slightly, then drag, and then find that there are some frames dropped.
I use dichotomy to find out where there is a problem.

I Use CDN to change Cesium verion and find the major version is 1.93 and build from source to find the problem commit became since [4a37d34]

sample codes:

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>

    <!-- <script src="https://cdnjs.cloudflare.com/ajax/libs/cesium/1.92.0/Cesium.js"></script> -->
    <script src="https://cdnjs.cloudflare.com/ajax/libs/cesium/1.93.0/Cesium.js"></script>
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/cesium/1.93.0/Widgets/widgets.min.css"/> 
</head>

<body>
    <div id="cesiumContainer"></div>
    <script>
        const viewer = new Cesium.Viewer("cesiumContainer", {
            imageryProvider: new Cesium.UrlTemplateImageryProvider({
                url: "https://a.tiles.mapbox.com/v4/mapbox.satellite/{z}/{x}/{y}.jpg?access_token=pk.eyJ1IjoienhqNTQ3MCIsImEiOiJja2N5bW9kcHEwYmRxMzFvdXVmbjhnbWh3In0.LA4oFRuHdvDBu558A-ux5Q",
            })
        });
    </script>
</body>

Well, so the bug since 1.93 has been fixed in 1.104 or 1.105 ?
But I try to change version to 105/106, the FPS is still aroud 50 by default code.
maybe I need to close atmosphere settings?

And try the latest version in sandcastle
(https://sandcastle.cesium.com/ latest version 1.115.0)

const viewer = new Cesium.Viewer("cesiumContainer");
viewer.scene.debugShowFramesPerSecond=true

still around 50 FPS

Thanks for the info @zxj5470!

We'll evaluate what more we can do to improve performance here. In the meantime, you can disable the atmosphere.
